In Exercise 1.20, perhaps refer to geyser as MASS::geyser (as you do on page 14 when the data is first referenced).
library(fastR2) enables access to the help file on geyser, but geyser itself does not get on the search path. (Because fastR2 depends on mosaic which in turn imports MASS?) This could stymie students.
